CitriSurf 77 Plus is a high quality blend of chemicals formulated for cleaning, rust removal and passivation of stainless steel products. It is provided in trigger sprayer bottles for applications where it is desired to spray the product on a local area. CitriSurf 77 Plus is specifically designed to provide a portable, low cost and efficient removal of contaminants and all rust and free iron from the surface of stainless steel, providing the highest chrome oxide levels possible.

Application Procedure: To assure best results the parts or areas to be passivated may be cleaned with an appropriate cleaning solution prior to treatment with CitriSurf 77 Plus solution, especially when heavy grease and oils are present.

The parts or areas to be cleaned and passivated should be sprayed, immersed or wiped with CitriSurf 77 Plus to completely wet the surfaces, especially in crevices or in areas where any rust or corrosion may have occurred. The surface must be soaked or left moist with the CitriSurf 77 Plus solution for a period of 15-30 minutes at room temperature. If heavy rust needs to be removed, Norton Bear-Tex Pads; or other non iron containing abrasive pads may be helpful. After soaking, rinse the surface with clean water. The surface can then be wiped dry with a clean cloth or appropriate absorbent medium. Allow the surface to air dry prior to use. CitriSurf 77 Plus will not harm the surface of stainless steel appliances or surfaces, and will enhance the brightness when used as directed. Use at full strength.

Testimonial

I just wanted someone to know that I tried your product on our Amana stainless steel refrigerator that had "rusted" or at least discolored. I let the Citrisurf 77 Plus stand on the surface 20 to 25 minutes and was thrilled that the product worked. The stainless was all brightened and the rust was gone. Thanks, the product is great.R.K.

A. Yes, tea staining is an early stage of stainless steel rusting. If you see tea staining, now is the time to remove the rust and passivate it.

Q. Are there any surfaces that CitriSurf is NOT compatible with?

A. CitriSurf will cause damage to the surfaces of concrete, carbon steel, zinc, and galvanized steel. Avoid exposure of these materials to CitriSurf and rinse immediately if there is an inadvertent spill onto these materials. CitriSurf can be used to clean carbon steel surfaces if care is taken to avoid overexposure, we recommend extra dilution and room temperature operation. PVC pipe and fittings made from copper, brass, or bronze are not recommended for long term use with CitriSurf.

Q. Are CitriSurf products safe to use on food equipment, do they leave a coating or residue?

A. CitriSurf may be used for these applications. When properly rinsed, no CitriSurf remains on the surface. The protective passive layer is formed from the metal itself.

Q. Will CitriSurf damage the surface of the stainless steel?

A. Unlike nitric acid based passivation, CitriSurf does not etch stainless steel and will not change the surface finish.

Q. What is the coverage of one bottle?

A. Coverage is approximately 50 square feet.

Q. I'd like to apply it to my stainless steel hinges on my fiberglass boat. Will it harm the fiberglass?

A. It won't harm fiberglass, not a problem.

Q. I was using bleach and splashed some onto my stainless steel refrigerator. At the time I didn’t think too much about it and just wiped it off. A couple of days later my refrigerator has rust all over the bottom. What is the best way for me to try to correct this issue?

A. Use CitriSurf 77 Plus to remove the rust and repassivate the affected area to help prevent the corrosion from returning.

Q. We have a Viking range with small rust blemishes and some discoloring. We live at the beach in Southern California and it looks like it may be from saltwater vapor damage. The stove is not very old and doesn’t get much use. What product would be best for our stove? Does it require scouring? How would you apply the product?

A. CitriSurf 77 Plus should be able to take care of your stove's corrosion. You simply spray the product onto the affect area, wait 20 minutes, and rinse it off. You may do some light scouring with a nonabrasive cleaning pad such as Norton’s Bear-Tex pads to help it along if you wish. Do NOT use a metal containing scouring pad as this will only create potential rust and corrosion.

A. The USDA Food Safety and Inspection Service has eliminated the requirement for prior approval of nonfood compounds for use in food processing plants. They now only require the product to be safe and effective under the conditions of use. This allows CitriSurf products to be used in food processing plants, saving money and improving safety. The USDA documentation on the requirement change can be found on their website.

Q. I have a set of 1820's antique brass andirons with lots of build up. What can you suggest that won't harm them?

A. Our CitriSurf 77 works very well on brass beds, we are told (see customer testimonial), and so it probably will do a good job on the brass andirons. We have no personal experience with brass, although some customers use our products on brass and bronze parts in industrial settings. We have sold quite a few bottles to people like yourself who have read the postings online of people who have used CitriSurf and had good results. There are many coatings placed over newer brass fixtures, we don’t believe that CitriSurf 77 will work on these types of materials.

Q. I have a stainless steel railing outside. What is the best product to protect and clean it so it doesn’t rust in time?

A. If you do not live near a coastline you're probably safe. If you do live near the coast, the salt air is a bad environment for stainless. One of the best things you can do is rinse it down with fresh water and SaltAway periodically to remove any salt. If you ever start to see some discoloration on the steel ("tea staining" corrosion), you should get some of our product CitriSurf 2310, which is very safe and easy to use and will take off the corrosion and fully repassivate the surface to forestall the return of that corrosion for as long as possible.
